Parabola

The parabola is a plane curved figure, where a set of points, on the curve, is equidistant from a
fixed point called focus, and also equidistant, in turn, when connected, to a fixed straight line called the directrix.
The parabola is represented, algebraically, by the Standard Form: y = a x2+bx +c.
Parabola elements:
Vertex: midpoint between the focus and the directrix;
Focus: fixed point F;
Focal parameter: distance between the focus and the directrix;
Directrix: fixed straight line;
Axis of simmetry: perpendicular line to the directrix passing through the focus.
To calculate the elements of a parabola, given the standard form, enter: a, b and c, using the point as a decimal separator. Example: 1350.38; the results will
be shown after a click on Calculate.
